Description

Technical Field

[0001] The utility model relates to the field of bubble water machines, in particular to a bubble water machine provided with a pneumatic lock body. Background Technique

[0002] A bubble water machine is a product that uses high-pressure carbon dioxide to dissolve in water to form carbonated bubble water. Such products generally include a main body and a water bottle. The water bottle is filled with water and then installed on the main body. A carbon dioxide gas cylinder and an air path main body are arranged in the main body. An air nozzle extending into the water bottle is arranged on the air path main body. By controlling the opening of the carbon dioxide gas cylinder, high-pressure carbon dioxide gas is injected into the water in the water bottle through the air nozzle. Therefore, during the operation of the bubble water machine, it is most important to stably install the water bottle on the main body. Moreover, after the preparation is completed, the residual air pressure in the water bottle needs to be discharged before the water bottle is removed. Otherwise, the residual pressure in the water bottle will drive the water bottle to explode outwards like a shell. However, there are always users who, when using it, install the water bottle improperly or remove the water bottle without exhausting the air, resulting in injuries to the users. Moreover, since the water bottle is a general part, there are often multiple manufacturers preparing it. However, there are always some water bottles with unqualified quality, resulting in cracking and injuring people after withstanding high air pressure multiple times. Content of the Utility Model

[0003] To solve the above problems, the purpose of the utility model is to provide a bubble water machine provided with a pneumatic lock body, so as to install the water bottle in a protective container, and the protective door cannot be opened when the air pressure in the water bottle is not discharged.

[0004] The technical solution adopted by the utility model to solve the problem is: a bubble water machine provided with a pneumatic lock body, including:

[0005] A main body, the main body includes an installation head, and an air path main body and an air nozzle located on the air path main body are arranged on the installation head;

[0006] A protective container, the protective container is located on the installation head, a protective cavity for accommodating the air path main body is arranged in the protective container, and an opening communicated with the protective cavity is arranged at the front end of the protective container;

[0007] A protective door, the protective door is movably arranged on the protective container to open and close the opening, and a lock hole is arranged on the protective door;

[0008] Locking valve member, the locking valve member is arranged on the protective container, and a locking valve cavity is arranged inside the locking valve member.

When the water bottle is installed on the installation head, it is communicated with the locking valve cavity through the gas guiding channel;

[0009] Elastic reset member, the elastic reset member is arranged inside the locking valve cavity. The elastic reset member is connected to the locking valve body and drives the locking valve body to move towards the port direction of the gas guiding channel. When the protection door is in the closed opening state, the valve hole is aligned with the locking hole.

[0010] As a further improvement of the above technical solution, a moving track is arranged on the surface of the protective container. The protection door is installed on the moving track, and the protection door moves along the moving track to open and close the opening.

[0011] As a further improvement of the above technical solution, the moving track is an annular track arranged on the top of the protective container. The top of the protection door includes an annular frame sleeved on the annular track.

[0012] As a further improvement of the above technical solution, the locking hole is arranged on the top of the annular frame.

[0013] As a further improvement of the above technical solution, the elastic reset member is a reset spring sleeved on the outer periphery of the valve stem. One end of the reset spring abuts against the valve head, and the other end abuts against the end of the locking valve cavity.

[0017] As a further improvement of the above technical solution, a handle is arranged on the surface of the protection door.

[0018] The beneficial effects of the present utility model are as follows: When in use, fill the water bottle with a specified amount of water, place it in the protection cavity of the protection container and install it on the installation head, then close the protection door. When injecting high-pressure carbon dioxide gas into the water bottle, the carbon dioxide gas will be transmitted to the locking valve cavity through the air guide channel, thereby pushing the locking valve body to move, causing the valve rod to extend along the valve hole and insert into the lock hole, and then locking the protection door. When the carbon dioxide gas in the water bottle is discharged, since there is no high-pressure gas pressing against the locking valve body, the locking valve body will reset under the action of the elastic resetting member, causing the valve rod to withdraw from the lock hole, and then the protection door can be opened normally. Through this solution, firstly, through the protection cavity and the protection door, even if the water bottle explodes, it will only explode in the protection cavity and thus will not hurt people. Secondly, the protection door can only be opened after the residual air pressure in the water bottle is emptied, thereby preventing the user from removing the water bottle when the air has not been exhausted.

[0031] Refer to Figures 1 to 7 , a sparkling water machine provided with a pneumatic lock body, comprising:

[0032] A main body 10, the main body 10 includes a mounting head 11, and an air path main body 12 and an air nozzle 13 located on the air path main body 12 are provided on the mounting head 11;

[0033] A protection container 20, the protection container 20 is located on the mounting head 11, a protection cavity 21 for accommodating the air path main body 12 is provided in the protection container 20, and an opening communicating with the protection cavity 21 is provided at the front end of the protection container 20;

[0034] A protection door 30, the protection door 30 is movably provided on the protection container 20 for opening and closing the opening, and a lock hole 31 is provided on the protection door 30;

[0035] A locking valve member 40 is provided on the protective container 20. A locking valve cavity 41 is provided inside the locking valve member 40. A gas guiding channel 42 extending to the gas path main body 12 is provided on the locking valve member 40. The end of the gas guiding channel 42 is located at one end of the locking valve cavity 41. A valve hole 43 is provided at the other end of the locking valve cavity 41. A locking valve body 44 is provided inside the locking valve cavity 41. The locking valve body 44 includes a valve head 441 and a valve stem 442 located at the bottom of the valve head 441 for cooperating with the valve hole 43. The valve head 441 is sealed with the inner wall of the locking valve cavity 41. When the water bottle is installed on the installation head 11, it is connected to the locking valve cavity 41 through the gas guiding channel 42.

[0036] An elastic reset member is provided inside the locking valve cavity 41. The elastic reset member is connected to the locking valve body 44 and drives the locking valve body 44 to move towards the port direction of the gas guiding channel 42. When the protection door 30 is in the closed and open state, the valve hole 43 is aligned with the lock hole 31.

[0037] During use, fill the water bottle with a specified amount of water, place it in the protection cavity 21 of the protective container 20 and thus install it on the installation head 11, and then close the protection door 30. When injecting high-pressure carbon dioxide gas into the water bottle, the carbon dioxide gas will be transmitted into the locking valve cavity 41 through the gas guiding channel 42, thereby pushing the locking valve body 44 to move, causing the valve stem 442 to extend along the valve hole 43 and insert into the lock hole 31, thereby locking the protection door 30. When the carbon dioxide gas in the water bottle is discharged, since there is no high-pressure gas pressing against the locking valve body 44, the locking valve body 44 is reset under the action of the elastic reset member, so that the valve stem 442 withdraws from the lock hole 31, and thus the protection door 30 can be opened normally.

On this basis, it is preferably that the moving track is an annular track 22 provided on the top of the protective container 20. The top of the protection door 30 includes an annular frame 32 sleeved on the annular track 22. On this basis, considering the rationality of the structural layout and reducing the amount of material used for the protection door 30, it is preferably further optimized that the lock hole 31 is provided on the top of the annular frame 32.

[0039] In other embodiments, the protection door 30 can also be pivotally connected to the protective container 20, so as to open and close the opening by swinging, but this requires a certain opening space.

[0040] For further optimization, it is preferred that the elastic resetting member is a reset spring 45 sleeved on the outer periphery of the valve stem 442. One end of the reset spring 45 abuts against the valve head 441, and the other end abuts against the end of the locking valve cavity 41. In other embodiments, the elastic resetting member can also be a pair of mutually attracting magnets, one of which is disposed at the end of the conduction channel and the other is disposed on the valve head 441.

[0041] For further optimization, it is preferred that a bottom outer sleeve 33 is provided at the bottom of the protection door 30. The bottom outer sleeve 33 is sleeved on the outer periphery of the bottom of the protection container 20, so that the protection door 30 also surrounds the bottom of the protection container 20.
